Sixth Street Viaduct & PARC

WHAT IS DTLA Forward?

DTLA FORWARD is a partnership with the City, community stakeholders, and strategic partners to achieve thriving and complete streets in Downtown LA. This transportation and planning initiative, launched by Councilmember Huizar, coordinates projects in the public realm.

Project Cost and Specifications: $484 million project to create new 3,500 linear foot replacement bridge, creating 12 acres of open space that will be home to the new Sixth Street Park, Arts, River, and Connectivity (PARC) Improvements Project.

Anticipated Timeline: Both the Bridge and the PARC are slated to be completed by the end of 2020

The Sixth Street Viaduct Replacement Project is the largest bridge project in the history of Los Angeles. The original Sixth Street Bridge, famous for its role in movies such as Grease, The Naked Gun, and Drive, was diagnosed with Alkali Silica Reaction (ASR), a degenerative condition where the bridge concrete separates and cracks, leading to major structural deficiencies. The city determined that it needed to be demolished and replaced with a new viaduct. Councilmember Huizar hosted an international design competition that aimed to create an iconic and world class bridge in LA. The winning design, by local architect Michael Maltzan in partnership with HNTB, is a ribbon of light.

The $484 million bridge will feature dedicated bike lanes, wide sidewalks, stairs and a bike ramp to the ground below, and arches that will be lit at night. The bridge features 10 sets of arches, all angled outward at nine degrees and is the first tied-arch base isolated bridge in the world. Councilmember Huizar saved over $20 million in state funds for the bike elements of the project and secured an additional $50 million in local funds to ensure that the design included all of the elements the public wanted.

Sixth St PARC

Spanning 12-acre underneath and adjacent to the new Sixth Street Viaduct, the Sixth Street Park, Arts, River and Connectivity Improvements Project (Sixth Street PARC) will connect Boyle Heights, the Arts District and the Los Angeles River with a giant new park and river access point.

Comprising of open space spread out across Boyle Heights, the Los Angeles River, and the Arts District, the $23 million park will complement the new bridge and be a world class destination. On the Downtown side, it will feature an Arts Plaza for performances, public access to the Metro Los Angeles River Bike Path, and connections to a potential 6th Street Metro Purple Line Station. Councilmember Huizar secured over $20 million for the design and construction of the park. The design team is led by Tetra Tech in partnership with Hargreaves and Associates and Michael Maltzan Architecture.

ENVIRONMENTAL REVIEW

The City of Los Angeles Bureau of Engineering is beginning the environmental review process for the proposed Sixth Street PARC Project. The City has determined that an environmental impact report (EIR) is required. A Notice of Preparation (NOP) and Initial Study (IS), which describe the Sixth Street PARC Project and the anticipated scope of the EIR, are available for public review and comment. This phase in the environmental review process is called the ‘scoping period’ (see figure below) and typically lasts 30 days.
